Quality control genotyping for assessment of genetic identity and purity in diverse tropical maize inbred lines
Quality control (QC) genotyping is an important component in breeding, but to our knowledge there are not well established protocols for its implementation in practical breeding programs. The objectives of our study were ...
Genome-wide association mapping reveals novel sources of resistance to northern corn leaf blight in maize
(BioMed Central Ltd, 2015)
Background: Northern corn leaf blight (NCLB) caused by Exserohilum turcicum is a destructive disease in maize. Using host resistance to minimize the detrimental effects of NCLB on maize productivity is the most ...
Assessment of management options on striga infestation and maize grain yield in Kenya
(Cambridge University Press, 2018)
The parasitic purple witchweed [Striga hermonthica (Del.) Benth.] is a serious constraint to maize production in sub-Saharan Africa, especially in poor soils. Various Striga spp. control measures have been developed, but ...
QTL mapping in three tropical maize populations reveals a set of constitutive and adaptive genomic regions for drought tolerance
Despite numerous published reports of quantitative trait loci (QTL) for drought-related traits, practical applications of such QTL in maize improvement are scarce. Identifying QTL of sizeable effects that express more or ...
Strategies to subdivide a target population of environments: Results from the CIMMYT-led maize hybrid testing programs in Africa
To develop stable and high-yielding maize (Zea mays L.) hybrids for a diverse target population of environments (TPE), breeders have to decide whether greater gains result from selection across the undivided TPE or within ...
Large-scale screening for maize drought resistance using multiple selection criteria evaluated under water-stressed and well-watered environments
A total of 550 maize inbred lines collected from global breeding programs were evaluated for drought resistance under both well-watered and water-stressed environments. The evaluation was based on multiple measurements of ...
Identification of drought, heat, and combined drought and heat tolerant donors in maize
Low maize (Zea maysL.) yields and the impacts of climate change on maize production highlight the need to improve yields in eastern and southern Africa. Climate projections suggest higher temperatures within drought-prone ...
Gains in maize genetic improvement in Eastern and Southern Africa : II. CIMMYT open-pollinated variety breeding pipeline
Open-pollinated varieties (OP Vs) still represent a significant proportion of the maize (Zea mays L.) seed system in many countries of sub- Saharan Africa. The International Maize and Wheat Improvement Centre (CIMMYT) has ...
On-farm yield gains with Stress-Tolerant Maize in Eastern and Southern Africa
Maize (Zea mays L.) is the most important staple food in eastern and southern Africa (ESA) with human maize consumption averaging 91 kg capita–1 yr–1. Current maize yield averages 1.2 t ha–1 and is barely suffi cient for ...
Relationship of line per se and testcross performance for grain yield of tropical maize in drought and well-watered trials
To optimize the efficiency of maize (Zea mays L.) drought breeding, the ability to predict testcross performance (TP) under drought stress using line per se performance (LP) of the parental inbreds would be useful. We ...
